ABSTRACT

THE AIM OF THE STUDY: Using the method of spectral-probability analysis, to evaluate the possibility of predicting an unfavorable outcome of acute decompensation of diabetes mellitus in patients hospitalized in the intensive care unit using a mathematical model. In relation to clinical practice, the implementation of the proposed algorithm for mathematical processing of a set of test data provides the physician with an additional significant criterion for assessing the probability of a tendency to develop type 1 diabetes in healthy children being examined whose brothers or sisters suffer from this disease.

MATERIALS AND METHODS: A retrospective analysis of 103 medical records of patients hospitalized in the intensive care unit for acute decompensation of diabetes mellitus was conducted.

RESULTS: With regard to the set of analyses of patients with acute decompensation of diabetes mellitus, carried out at the time of admission to hospital, a group of mathematical criteria has been defined that makes it possible to identify patients with a high risk of an unfavorable course of the disease.

ABSTRACT

BACKGROUND: It has been proposed that nursing students experience emotional and mental issues due to their educational demands, which influence their academic success. This study aims to explore the relationship between students’ attitudes and intentions toward seeking professional psychological help and focus on exploring a mediating role of emotional intelligence.

METHODS: This study used a descriptive correlational design. A convenience sample was used to recruit 514 undergraduate nursing students in the central region of Saudi Arabia. Data were collected using self-administered tools from three nursing colleges. Data were analyzed using both descriptive, inferential, and structural equation modeling statistics.

RESULTS: The current study results indicate that university students had moderate positive attitudes, moderate positive intentions toward seeking help for mental health concerns, and a positive level of emotional intelligence. Attitudes toward seeking help and emotional intelligence had a significant positive relationship on professional mental help-seeking intentions. Other factors that predict students’ intention to seek help include the history of consulting a mental health professional and students who were unsure of the availability of the on-campus counseling center (p <.001). Emotional intelligence has a significant mediation effect on the relationship between mental help-seeking intention and mental help-seeking attitudes toward professional psychological help.

CONCLUSIONS: Based on the results, students with emotional intelligence and positive attitudes toward seeking mental help were significantly correlated to their intentions of seeking professional mental help. This study proposes the importance of implementing interventional programs to increase nursing students’ intentions to use the university counseling center for optimum mental health and well-being.

ABSTRACT

Sustainable biosynthesis of metal oxide nanoparticles using an eco-friendly approach is a growing research area owing to their promising environmental and biomedical applications. This work aims to biosynthesize and characterize magnesium oxide nanoparticles (MgONPS@Aj) for possible application in dye biosorption and antibacterial activity. For the first time, MgONPS@Aj was successfully synthesized by harnessing exometabolites of Aspergillus japonicus. Various parameters were statistically optimized to maximize the production of MgONPS@Aj using Plackett Burman’s design and central composite design. The analysis of variance (ANOVA) revealed that pH was the most significant variable, affecting the bioproduction process followed by biomass quantity and Mg²⁺ precursor concentration. The suggested model (quadratic) was greatly significant and acceptable due to the nonsignificant lack of fit (15.10), and P-value (0.001). The optimized nanoparticles were characterized using X-ray powder diffraction, Fourier-transform infrared (FTIR) spectroscopy, transmission electron microscope (TEM), and Scanning electron microscopy. A high biosorption capacity (204.08 mg/g) of reactive black 5 dye was achieved within 40 min using a 5 mg biosorbent dose (MgONPS@Aj), 100 mg/l initial dye concentration, and pH 6.0. The biosorption process followed a pseudo-second-order (R² of 0.9842) and Langmuir isotherm (R² of 0.9422) models with a dimensionless separation factor (R_L) of 8 × 10⁴, hinting favorable and effective biosorption of dye molecules. A biosorption capacity of 81.97 mg/g after five successive cycles hints that the nanomaterial is suitable for several time utilization. Biogenic MgONPS@Aj displayed dramatic concentration-dependent antibacterial activity with the largest inhibition zones for P. aeruginosa (24.1 ± 0.8 mm, MIC: 3.125 µg/ml), followed by E. coli (22.3 ± 0.7 mm, MIC 6.25), B. subtilis (14.7 ± 0.4 mm, MIC: 12.5 µg/ml) and S. aureus (19.2 ± 0.6 mm, MIC: 6.25 µg/ml). The antibacterial activity was further interpreted using molecular simulation analysis. The lowest binding affinity was determined between MgONPS@Aj and target bacterial proteins (chloramphenicol acetyltransferase E. coli, and S. aureus MurE). The ligand (MgONPS@Aj) can bind to the active site’s residues (Tyr¹⁷² and SER²²⁴), indicating a possible antibacterial mechanism. This study recommends MgONPS@Aj as an eco-friendly, and reusable alternative to traditional anionic dye sorbents and a uniquely promising candidate for antimicrobial applications.

ABSTRACT

BACKGROUND: Promoting essential newborn care practices is one of the effective approaches to improving child health outcomes, especially in low-resource areas. This study aims to assess the determinants of essential newborn care practices among mothers in a peri-urban community in Ghana.

METHODS: This descriptive community-based cross-sectional study design used 280 mothers within the Kukuo community in the Tamale metropolis selected through convenience sampling technique. A pretested questionnaire was used for data collection. Data was entered into EpiData version 3.1 and cleaned before being imported into IBM SPSS Statistics Version 26.0 for analysis. The univariate chi-square test and t-test statistic were used to determine the likelihood of practising essential newborn care among mothers. Statistically significant statistics at p-value ≤ 0.05 were modelled using multivariable regression.

RESULTS: Mothers (77.2%) identified the immediate care given to a newborn as essential newborn care. The study revealed that mothers had good knowledge (50.7%) and good practices (60.7%) of essential newborn care. Mothers between the ages of 25-29 years (AOR 1.18; 95%CI 0.35-4.01), had tertiary education or above (AOR = 5.2; 95%CI 1.36-18.49), and traders (AOR = 1.41; 95%CI 0.45-4.42) were more likely to practice good essential new-born care than their counterpart. Also, having good knowledge of ENBC (AOR = 11.57, 95%CI 5.21-25.70) and knowing danger signs in newborns (AOR = 4.62, 95%CI 2.26-9.45) was significantly associated with essential new-born care practice.

CONCLUSION: The study’s outcome revealed that mothers had adequate knowledge of essential newborn care, appropriately identified the danger signs in newborns, and practised good essential newborn care. Interventions to improve newborn care must segregate mothers and target specific client knowledge as significant differences were found based on knowledge, education level, and employment type.

ABSTRACT

BACKGROUND: The arthroscopic treatment of shoulder instability is widely debated in the literature and includes very different surgical techniques. Imaging techniques do not allow an accurate assessment of soft tissue quality. The aim of the study is to demonstrate that correct patient selection and a surgical technique involving anterior and posterior capsular ligament repair with axillary retention may be the most crucial factors for successful arthroscopic treatment.

METHODS: Patients with recurrent shoulder instability who underwent arthroscopic stabilization between 2014 and 2015 and aged between 15 and 25 years, were included. The minimum follow-up was 5 years. Specific exclusion criteria were critical bone loss and patients with genetic connective tissue disorders. Demographics, instability characteristics, surgical procedures, recurrences, both dislocations and subluxations, and surgical revisions were evaluated. The surgical procedure, always performed by the same surgeon, involved the use of a minimum of 3 double-suture fixation devices and repair/tensioning of the axillary hammock. Statistical analysis was based on the non-parametric Kendall statistical model and proportions test, with p < 0.05.

RESULTS: The study population consisted of 44 patients. The first dislocation occurred in 61.4% of cases between the ages of 15 and 19. The number of dislocations prior to surgery was < 3 in 29.5%, between 3 and 9 episodes in 25%, and 10 or more episodes in 45.5%. Defined by patients who had no recurrent dislocations and those whose symptom of instability or subluxation did not require surgical revision, the surgical success rate was 90.9%. During the follow-up period, 4.5% of patients required surgical revision. Patients who required none or one reduction maneuver or had less than three dislocation episodes were statistically correlated with no recurrences after surgery. After the first dislocation, the 88.6% of patients had recurrency. Furthermore, if treated after only one episode, 75% of patients were affected by an isolated capsulolabral injury. Prompt stabilization surgery allows a simpler procedure, due to a reduced bone damage and associated injuries.

CONCLUSIONS: Even in a high-risk age group under 25 years, when the bone defect is subcritical, performing a standardised surgical technique including antero-posterior capsulolabral repair with axillary hammock retensioning demonstrates high success rates. Patients who correlate with the highest chance of success are those who have had less than three dislocation episodes and who have not undergone reduction manoeuvres, confirming the importance of soft tissue quality and thus of early treatment.

ABSTRACT

BACKGROUND: People who inject drugs (PWID) are more likely to engage in unsafe sexual behavior placing them at high risk of acquiring HIV and other STIs. This study aims to assess the prevalence and predictors of inconsistent condom use with casual and/or paid sexual partners among PWID in Georgia.

METHODS: Integrated Bio-Behavioral Surveillance Survey was conducted among PWID in seven major cities of Georgia. Study design was cross-sectional with respondent-driven sampling (RDS) methodology. Data collection was carried out through individual face-to-face interviews. Of the 2005 PWID who participated in the study, we analyzed a subsample of 619 (30.9%) who reported having casual and/or paid sexual partners during the last 12 months and described prevalence and predictors of consistent condom use.

RESULTS: Consistent condom use during casual and/or paid sex in past 12 months was reported by 49.4% of respondents. The likelihood of consistent use with casual and/or paid sexual partners was statistically significantly associated with residence, family income, drug use frequency, drug dependence and HIV risk self-perceptions. In multivariable analysis independent predictors of always using condom at casual/paid sex during the last 12 months were place of residence (aOR = 6.4; 95% CI: 3.2-12.7), family income (aOR = 2.1; 95% CI:1.3-3.5) and drug use frequency (aOR = 0.6; 95% CI: 0.4-0.9).

CONCLUSION: The study revealed low prevalence of consistent condom use with casual and/or paid sexual partners among PWID in Georgia. Integration of safe sex educational interventions in harm reduction services may improve the rates of condom use among PWID and should focus PWID with lower socio-economic status and residing outside capital city.

ABSTRACT

The enhancement of rice quality stands as a pivotal focus in crop breeding research, with spectral analysis-based non-destructive quality assessment emerging as a widely adopted tool in agriculture. A prevalent trend in this field prioritizes the assessment of effectiveness of individual spectral technologies while overlooking the influence of sample type on spectral quality testing outcomes. Thus, the present study employed Microscopic Hyperspectral Imaging, Raman, and Laser-Induced Breakdown Spectroscopy (LIBS) to acquire spectral data from paddy rice, brown rice, polished rice, and rice flour. The data were then modeled and analyzed with respect to the amylopectin and protein contents of the rice samples via regression methods. Correlation analysis revealed varying degrees of correlation, both positive and negative, among the three spectral techniques and the analytes of interest. LIBS and Raman spectroscopy demonstrated stronger correlations with the analytes compared to microscopic hyperspectral imaging. Based on the selected correlation variables, feature screening and regression modeling were conducted. The modeling results indicated that microscopic hyperspectral data modeling yielded the lowest coefficient of determination of R² = 0.2, followed by Raman data modeling result was higher than it, which was about 0.5. The modeling effect of polished rice is the best. LIBS data modeling performed best, with a coefficient of determination of 0.6. The influence of different sample types on the modeling results was less than that of Raman spectroscopy, and modeling results of grains were better. The feature matching analysis of Raman and libs spectroscopy techniques showed that there were spectral variables that could match amylopectin and protein in the features obtained by multiple modeling statistics, but some modeling variables failed to match. LIBS matched more variables than Raman. These findings provide valuable insights into the application effectiveness of different spectral techniques in detecting rice contents across diverse sample types.

ABSTRACT

BACKGROUND: Although gratitude is a culturally-sensitive construct, it has yet received limited research attention in Arab countries, hence hindering the understanding of its features, correlates, and cross-cultural specificities. To fill this gap, we sought to examine the psychometric properties of an Arabic translation of the 6-item Gratitude Questionnaire (GQ) in an Arabic-speaking sample of adults from the general population of Lebanon.

METHOD: We conducted a web-based survey including 601 participants (mean age 29.91 ± 12.61, 62.7% females). The forward-backward translation method was used for the translation and adaptation of the GQ-6 into the Arabic language.

RESULTS: Findings indicated that a four-item version of the GQ achieved adequate fit statistics with the removal of the two reverse-scored third and sixth items. We found a McDonald Omega coefficient for the total 4-item GQ (GQ-4) scores of 0.88, thus attesting for the good reliability of the scale. Multiple-group Confirmatory Factor Analysis showed that the scale structure was invariant across male and female respondents at the configural, metric, and scalar levels. Females exhibited significantly higher gratitude scores compared to males. Finally, discriminant validity of the Arabic GQ-4 was evidenced through positive significant correlations with social support levels.

CONCLUSION: The Arabic adaptation of the GQ showed good psychometric qualities, suggesting that it is suitable for measuring people’s disposition toward gratitude in Arab backgrounds. Offering the Arabic GQ-4 as a brief, simple, cost-effective, valid, and reliable measure of gratitude to the Arabic-speaking community could help raise awareness about gratitude as a key component for achieving good mental health and wellbeing in Arab contexts.

ABSTRACT

BACKGROUND: The purpose of this study was to clarify the potentially life-saving critical interventions performed on children below the age of seven by the physician-manned mobile emergency care unit (MECU) in Odense, Denmark. We investigated critical interventions in relation to morbidity and mortality.

METHODS: A retrospective cohort study of all MECU missions involving children below the age of seven. The study period was from October 1 2007 to December 31 2020. Data sources were the MECU Odense database, the Danish National Patient Registry, and the Danish Civil Registration System. Variables were critical interventions, the severity of injury/illness, MECU on-scene time, in-hospital diagnosis and 7-day, 30-day, and 90-day mortality.

RESULTS: The MECU carried out 4,032 missions to children below 7 years. 88 patients (2.2%) received at least one critical prehospital intervention. Upper airway suction was performed in 39 cases (1.0%), endotracheal intubation (all causes) in 36 cases (0.9%), and intraosseous access in 21 cases (0.5%). General anaesthesia was induced in 29 cases (0.7%). Seventeen patients (0.4%) received cardiopulmonary resuscitation and two patients received manual defibrillation (< 0.1%). 3,278 patients were admitted to the hospital and assigned a diagnosis when discharged. The most common diagnoses were assigned within the International Statistical Classification of Diseases and Related Health Problems 10th Revision Chapter XVIII (Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified), which includes febrile convulsions. 1,437 patients (43.8%) were assigned diagnoses within this diagnosis group. The overall 7-day mortality in the cohort was 0.74%, 30-day mortality was 0.82%, and 90-day mortality was 1.02%.

CONCLUSION: Prehospital critical interventions are rarely performed in children under the age of 7 years. The low frequency of these interventions may have implications for maintaining the clinical routine of the prehospital care providers.

ABSTRACT

BACKGROUND: Bone lengthening and free vascularized fibula graft (FVFG) represent two prevalent modalities for bone defect repair. The objective of this study was to compare the efficacy disparities between FVFG and single – segmental bone lengthening (BL) when the Orthofix external fixator was utilized in the treatment process.

METHODS: The follow – up data of 72 patients with femoral defects, who received treatment from January 2009 to May 2019, were collected for retrospective analysis. Among them, 60 comparable patients were stratified into two groups: one group of 30 patients received free vascularized fibular graft in combination with Orthofix external fixation (FVFG group), and the other group of 30 patients underwent single – segmental bone lengthening using the Orthofix external fixator (BL group). The specific aspects evaluated encompassed operation time, intraoperative blood loss, postoperative Activities of Daily Living (ADL) score, assessment by the Association for the Study and Application of the Method of Ilizarov (ASAMI), limb length discrepancy (LLD), external fixation index, bone union status, and complications.

RESULTS: 1.Surgical – related indicators: The mean operation time in the FVFG group ( 5.04 ± 1.22 h) was significantly longer than that in the BL group (1.58 ± 0.56 h, p<0.001). The intraoperative blood loss (450 ± 190.73 ml) in the FVFG group was substantially higher than that in the BL group (120 ± 46.23 ml, p<0.01). Although the duration of external fixator use in the FVFG group (16.9 ± 3.52 months) was marginally longer than that in the BL group (15.53 ± 2.09 months), this difference did not reach statistical significance (p=0.073). 2.Postoperative complications: According to the Paley classification system, no significant differences were observed between the two groups in terms of nail infection, nail loosening, limb edema, nonunion (including nonunion in the BL group and fibula nonunion in the FVFG group), and postoperative fractures. All complications were effectively managed through appropriate treatment strategies. 3.Functional evaluation: Based on the ASAMI criteria, the excellent – to – good rate of bone outcomes in the FVFG group was 80.0%, while the BL group demonstrated superior results (p = 0.028). The excellent – to – good rate of limb function in the FVFG group was 36.6%, and there was no significant difference between the two groups (p = 0.537).

CONCLUSION: For the treatment of femoral defects measuring ≥ 6 cm, single – segmental bone lengthening with the Orthofix external fixator exhibited advantages in terms of shorter operation time and reduced blood loss compared to FVFG combined with the Orthofix external fixator. Although other outcomes were comparable between the two groups, FVFG demonstrated broader applicability across diverse bone defect classifications, primarily constrained by the defect length and the vascular condition of the recipient site.
